Another way is to catch roach in jar put in some type of detergent,[eg liquid hand soap or dish washing detergent] then fill with water. the roach drowns because the soap does something to the surface tension of the water. The roach can't float to the top and run away

My gf, who has a degree in restaurant/hotel management, and works as a sous chef at a 4 star restaurant, says stepping on them only allows the eggs to stick to your shoe if the roach is female and pregnant. You then carry them back to your house or spread them around. We live in an old converted school building now artist studios. When we see a roach, we cap it with something clear. Then we slide paper or thin cardboard under the clear dome and carry it to the toilet and flush it. They can hold their breath for quite some time, but at least it's gone.

OMG! I never considered that! Now I have to sterilize my shoes!
Another little fact to consider. If you're ever offered Paper or plastic at the grocery, you might think environment and say paper... DON'T!!! Roaches love the glue used to hold those bags together. They not only feast on it, but lay their eggs in it. On the other hand, the plastic used in modern grocery bags is 100% biodegradable in a very short time it dissolves into CO2 and if burned emits only CO2.
